Alcohol based no-clean liquid fluxes
959T – recommended for general use
Kester 959T is a no-clean, non-corrosive, halogen free liquid flux that is designed for the wave soldering of conventional and surface mount circuit board assemblies. Kester 959T was developed to minimize the formation of micro-solderballs during wave soldering operations. This flux contains a small percentage of rosin (1%), which improves solderability, heat stability and surface insulation resistance. Kester 959T offers the best wetting and the shiniest solder joints of any no-clean, solvent-based chemistry. Kester 959T leaves evenly distributed residues for the best cosmetic appearance.
952S – recommended for PV solar
Kester 952 S is a halogen-free, non rosin organic flux designed for wave soldering conventional and surface mount circuit board assemblies. The extremely low solid content (2%) and nature of activator system results in practically NO RESIDUES left on the assembly after soldering. Boards are dry and cosmetically clean as they exit the wave solder machine. There are no residues to interfere with electrical testing and the expense of cleaning is eliminated.
Kester 952 S is exhibiting improved soldering performance to minimize soldering bridges (shorts) and excessive solder defects. This non-corrosive and non conductive flux meets the strictest requirements of Bellcore TR-TSY-000078 specification. This flux is suitable for automotive, computer, telecommunications and other applications where
reliability considerations are critical. The surface insulation resistance on soldered boards is higher than that provided by typical organic water-soluble fluxes.
